-Although I have described my improvements in great detail and with respect to 70 certain particular forms 'of my invention, nevertheless I do not desire to be limited to such details except as clearly pointed out in the appended claims, sincemanvchanges and modiiicationsmay well be made Without 75 departing from the spirit and scope of .my invention in its broadestaspect.

Having fully and clearly described my improvements, what. I claim as new and desire-to secure by Letters Patent, is: o

l. A cooking grill having a heat storage mass provided with a series of substantially parallel-grilling ribs, an electrical heating element extending along and substantially within each rib for heating the mass, and 8'5 heat insulatinf,a means partially surrounding said mass. l

l 2. A cooking grill having a solid unitary heat storage mass provided 4with grilling ribs on one face thereof, electrical heating' 90 elements extending within saidl mass, heat insulating walls covcringthe bottom and sides of said mass, a heat insulat-ing cover fitting closely over the top of the mass.

3. A cooking grillhaving a solid unitary` 95 heat storage mass provided with grilling l ribs. on its top surface, electrical means for internally heating said -nass, meansV for holding one end of the mass elevated whereeccnomically'and quickly brought to the-desired temperature.-` Thereupon the cover is thrown back, as shown in Fig. 5 or Fig. 6, and 'the material to be grilled is placed upon 5 the grilling ribs 2 and cooked'in the usual manner. During the cooking vthe supply of electric energy may be t turned 'y oit1 and the cooking done with' the heat which has vbeen already stored in the mass l, or if desired le the currentl may be left on to continually supply heat to the mass l. lt;will therefore appear that due to the preliminary heating the cover l0 becomes more or less heated, and whilethe cooking operati-on is proceeding the coverlO may be used for the vpurpose of heating plates 23, orthe like, as shown in Figs. 5 and 6, If it is desired to fry or heat kettlcs or thelike the plug 1S is removed vand the storage massl. turned 2o upsidev down,l whereupon a flat surface is presented for heating or cooking. The plug is then inserted again to electrically conneet thev heating elements, and the storager .mass broughtl to the proper temperature as abovedescribed.y The cover'- may be then thrown back and the frying operation per-- top of themass l, or kettles or other cooki ing vutensils may be placed upon the storage se) mass l, to beheated for cooking purposes. 'instead of providing the heating elements t in longitudinal holes in the ribs 2, the electric' resistance Wires may be placed just below the, ribs 2 in a relatively'thin, Hat compartment 24,'as illustrated in Fig. ft. From the above itwill be clear that the grill or heat storage masscomposed of lire clay or other refractory material, is adapted to be entirely inclosed'in a casing vof heat in- 40 sulating material While it is being preliminarily heated in order to .raise its temperature'suiiiciently for grilling or other heating purposes,` and to be'only `exposed by opening the covering or casing in order to allow the grillingjor other heating operation to be effective; l I

l/Vhen it is desired to grill a steak or lother article'of food,'the supports orlegs 16 may `be'swung downward, and serve to support 60 the grill in an inclined position, whereby any gravy or juice may run downalong the "V shaped'grooves to thechannel 17, and thence out by the groove 15', and any smoke or fumes that may arise along the V shaped grooves may escapel into the air fromv the upper en'd of the grill. When the grill l is reversed thlfsarme may be used for heating a frying pan or-kettle,lor other vessf-:Lsory for toasting, as will be readily understood. A device constructed according to this invention'consumes only a very small amount of power and may be used in heating systems comprising an electrically heated oven. Such ovens rcan be sulticiently heated at a; se consumptionA of about 400 Watts per' hour,

means being hinged wherebyA the mass may be placed in horizontal position.

A1l. A cooking device having a relatively flat heat storage mass ofv solid material with grilling ribs thereon, electrical resistance 105 means for internally heating said mass, heat insulating means surrounding said mass on the bottom and sides thereof, and a heat insulating cover for the top. of the mass adapted to fit closely over the same. 1 v 110 5. A cooking grill having a heat storagemass provided with ribs' on one side thereof, electrical conductors extending within thev massfor heating the mass internally, a-he'at insulating covering',surrounding the bot- 115 tom and sides ofthe mass, and a heat insulating cover for the top of the mass, said -cover being movable to permit the' placing .of the material on'thc grill forv cooking, after the mass has been heated. 12o

G. A cooking grill having a' heat storage mass of solid material, means for heating the mass electrically, a covering of heat insulating material substantially entirely suirounding the' mass, and means whereby a 125 portion of said covering may be removed to permit of the material to be cooked being vplaced onthe grill. to be heated by the storage mass, said mass-having grilling ribs on one sidel thereof and a cooking face'on 130 by the grill maybe inclined, said holding the other side thereof whereby the mass I. may be turned upside down in the covering and different cooking operations performed on both sides thereo 5 7. vA cooking device having a heat storage mass, means for electrically heating vthe mass, and a heat insulating casing extending about thesides and bottom of said mass, said mass having a cooking face on both sides thereof and adapted to be turned upside down, whereby cooking operations may be carried out on both sides of the mass.

-8. A cooking grill having a heat storage mass, electrical resistance heating elements in said mass, said mass being provided with grilling ribs on one side thereof, and a heat Copies of this patent may be'obtained for extending about the botsaid mass, said mass hav-1 ing a coo-king face on the opposite side thereof from the `grilling ribs and being adapted to be turned upside down in the casing whereby other cooking operations may be performed on the opposite side thereof from the grilling ribs. y

In testimony whereof, I have signed my name to this specification, in the presence o two subscribingjwitnesses.
